Answer:
A)   v = 40 m / s, B)   v_average = 20 m / s
Explanation:
For this exercise we will use the kinematics relations
          
A) the final velocity for t = 5 s and since the body starts from rest its initial velocity is zero
          v = vo + a t
          v = 0 + 8 5
          v = 40 m / s
B) the average velocity can be found with the relation
          v_average = vf + vo / 2
          v-average = 0+ 40/2
           v_average = 20 m / s
 
        
             
        
        
        
Answer: option d.  Explanation:
Explanation:1) The 
direction of the 
field lines inform about the 
sign of the charges.
The field lines <span>
extend from the positive charges to the negative charges, so you can conclude that the charge C is positve and both charge A and charge B are negative:

</span><span>
</span><span>Charge C: positive
</span><span>

</span><span>
</span><span>Charge B: netative

2) The 
density of the lines (number of lines in a region) inform about the 
magnitude of the electric field.
Since the charges are at the same distance, the magnitude of the electric field informs directly about the magnitude of the force and that about the magnitude of the charges.
Since, there are the 
double of lines between C and B than between C and A, the magnitude of 
charge B is the double than the magnitud of charge A.
From the five options given (a throug e) the only that is consistent with that charges A and B have the same sign, that charge C has different sign, and that charge B is the double of charge A is:
 
 
        
             
        
        
        
Answer:

Explanation:
The spaceship has traveled 3% of the distance to a space station and it has traveled  miles.
 miles. 
Let the total distance from the ship's starting point to the space station be x.
This means that:

The total distance to be traveled is  .
.
Therefore, the distance left to travel is:

 
        
             
        
        
        
Answer:
The weight is the gravitational force with which a body is attached to the Earth (planet/moon) Weight of any object on earth depends on two factors mass and gravitational constant. As per law, W = mg where, g is gravitational constant 9.8 m/s/s
